Hi Alex, Thanks for the reply. I should state I am using vanilla apache hadoop 2.4.0 and hive 0.13.1 (not Horton works). And I don't have root access on my pseudo distributed hadoop cluster (single node).
I tried your suggestion for a query: hive> explain select count(*) from web_sales; Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tez/dag/api/client/StatusGetOpts I'm thinking I must install Tez separately from source. And then set the env vars and HADOOP_CLASSPATH as per: http://dev.hortonworks.com.s3.amazonaws.com/HDPDocuments/HDP2/HDP-2.1.2/bk_installing_manually_book/content/rpm-chap-tez_configure_tez.html Tim From: Alexander Alten-Lorenz <wget.n...@gmail.com<mailto:wget.n...@gmail.com>> Reply-To: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>>, Alexander Alten-Lorenz <wget.n...@gmail.com<mailto:wget.n...@gmail.com>> Date: Wednesday, July 16, 2014 11:27 PM To: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>> Subject: Re: Turning on Tez for Hive Just use the execution engine, can be done per Hive query too: hive > set hive.execution.engine=tez; hive > select count (*) from what_ever; If you want to use HS2 with Tez, follow the documentation here: http://dev.hortonworks.com.s3.amazonaws.com/HDPDocuments/HDP2/HDP-2.1.2/bk_installing_manually_book/content/rpm-chap-tez-configure_hive_for_tez.html - Alex ------ Originalnachricht ------ Von: "Tim Harsch" <thar...@yarcdata.com<mailto:thar...@yarcdata.com>> An: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>> Gesendet: 17.07.2014 01:09:07 Betreff: Turning on Tez for Hive Hi all, Is there a wiki page somewhere that shows how to turn on Tez for Hive? I found "hive.execution.engine" in hive-default.xml.template. But I'm sure there must be more. Do I have to install Tez separately? Thanks, Tim
